SHOCK-LOADER.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed March 17, 1914, Serial No. 825,363. Renewed May 17, 1916. Serial No. 98,216.

To all whom it may concern 1 Be it known that I, MARTIN C. ALBEa'rson, a subject of the King of Great Britain, residing at Gray, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improve-V ments in Shock-Loaders, of which the following is a specification.

This invention relates to shock loaders and is a divisional portion of my parent application for shock loaders, filed January 10, 1913, Serial No. 741,326.

The principal object of this invention is to associate with the receiving end of the endless shock carrier, a suitable 1 pick-up mechanism which gathers the grain from 11-- the ground and deposits it on the carrier,

the pick-up mechanism being simultaneously actuated with the actuation of the carrier by the traction of the vehicle on which the carrier is mounted.

A further object of the invention is to associate with the pick-up mechanism a suitable means by which the plane of operation of the pick-up fingers or tangs may be altered in order to adapt the deviceforhandling shocks of various sizes, weights, etc;

d Other objects as well as the nature, characteristic features and scope of the invention will be more readily understood from the following description taken inconnection with the accompanying drawings and pointed out in the claims formlng a part of this specification. i

Referring to the drawings: ljhgure 1 1s a top plan view of my improved plck-up mech anism showing the same operatively connected with theshock carrier; Fig. 2 is a fragmentary longitudinal sectional view of the drum showing the fingers or tangs in plan and their connection with the operat ng element and Fig. 3 is a fragmentary side elevational View partly in section of my 1mproved device, showing the pickup mechanism raised fromthe earth and illustrating the manner in which the pickup mechanism is associated with the carrier frame.

In the drawings wherein is shown the preferred embodiment of this invention in order to illustrate the application thereof a portion of the draft beam 5 is provided which is in connection with a portion of a carrier frame 5 said beam having associated therewith a bearing 6 in which is revolubly mounted one end of a shaft 7, said shaft having the intermediate portion thereof depressed to provide a 'U-shaped structure one arm 8 ofwhioh, as previously pointed out is in engagementwith the bracket 6 while the opposite arm 9 is inengagement with the carrier frame, while a reciprocable rod 10 is associated with said arm the free end of which is adapted for sliding engagement with said carrier. Tracks 11 of the carrier are arranged above the intermediate portion of the shaft 7, chains 12 riding over said tracks and having engagement with sprocket wheels 13 which are carried by the driven shaft 14, said shaft 14 being supported by the carrier through the medium of bearing arms 15, the latter extending beyond the shaft 14 and provided on the extreme outer ends thereof with sleeves 16, which are engaged with the trunnions 17 of the drum 18.

My improved pick-up mechanism in the present instance comprises the cylindrical drum 18 which is provided with diametrically'opposite and uniformly spaced apart apertures 18 through which are engaged fingers or tangs 19 the latter being engaged with a longitudinally extending bar 20, the tangs onthe opposite ends of the bar 20 being in revoluble engagement with links 21 through the medium of the pins 21, said links having enlarged ends 22 which are pivotally engaged with similar enlarged ends 23 on shafts 24:, said shafts extending through the trunnions 17 and having the extreme outer ends thereof in engagement with levers 25, said levers being each in con nection with one end of a rod 26 the opposite end of each of said rods being turned at right angles to the body to provide a hook which is engaged in the apertures 27 of the plate 28. i

Mounted on the outer end of each of the trunnions 17 is a sprocket wheel 29 which is fixedly secured thereto and has trained thereabout a sprocket chain 30, saidchain being likewise trained over i a sprocket wheel 31 which is carried by the driven shaft 14. It

therefore seen that when motion is imparted to the shaft 1 1 through the actuation of the chains 12 that the drum 18 will be revolved causing the tangs 19 to be reciprocated through the apertures in the periphery of the cylinder 18 so as to pick up shocks of grain which lie in its path of movement. It is of course understood that the tangs 19 are fixedly carried by the bar 20 so as to be simultaneously operated with the actuation of said bar when motion is imparted to the tangson the opposite ends thereof.

In order to retain the shafts 21 against rotation or to alter the position of the enlarged ends 23 which are formed on the in nor ends of the shafts 24, the rods 26 are engaged with the desired apertures 27 of the plates 28 thereby causing the pinsto engage the enlarged ends 23 of the shafts 24 with the enlarged ends 22 of the links 21 to be brought nearly or be moved farther from a plane passing horizontally through the axisof the drum thereby altering the position of the tangs with respect to the periphcry of the drum. This action enables the pick-up mechanism to be adapted for successful operation, according to the size or weight of the shock which is being engaged by the tangs19.

In Fig. 3 the pickup mechanism is associated with a carrier frame heretofore mentioned, which has mounted therein an endless carrier or conveyor 32 to which motion is imparted by the traction of the vehicle through a mechanism (not shown) the pickup mechanism being shown disengaged from the ground in this view, in which position it is held through the medium of a pawl andratchet mechanism generally designated 33. The pawl and ratchet mechanism is mounted on the draft beam5 inproximity to the operators seat 3 1, so as to be readily actuated by the operator when so desired. A- rod 35 connects the pawl and ratchet mechanism to one end of a bell-crank lever 36, the opposite end being in pivotal connection with the end S of the member 7 through the instrumentality of a link 37. A wheel 38 is carried by the end 9 of the shaft 7, so that when the pickup mechanism is disengaged from the earth, movement of the vehicle is permitted in view of the fact that by depressing the shaft 7 intermediate its ends, it is seen that the opposite ends 8 and 9 thereof are offset, thereby causing the wheel 38 to be thrown into engagement with the earth when the pickup mechanism is disengaged therefrom. In operation therefore, assuming that the drum 18 has the tangs 19 thereof in engagement with the earth, the traction of the vehicle causes the drum to be revolved in view of its operative connection with the conveyer or carrier 32,

I thewl'ieel 38 to be automatically, engaged with the earth in which position it is held from displacement in. view: of thepawl and ratchet mechanism 33. It will be understood that the above description and. accompanying drawingscomprehend only the general and preferred embodiment of. my invention and that various minor changes in details of construction, proportion and ar rangement of the parts may be madewithin thescopeof the appendedclaims and without sacrificing any of. the advantages of my invention.

' 'laving thus fully described invention what I claim as new and desire to secure by Letters Patent is 1.
